a Permeability of C57 and Slit2 mouse brains. The data represent the mean results from seven mice; bars, SE. **, P <0.01.
b Measurement of the ICH area in brain longitudinal section slides from C57 and Slit2 mice. The data represent the mean results from six mice; bars, SE. **, P <0.01.
c and d Longitudinal section slides of mouse brains in which ICH was induced. The ICH area was bigger in Slit2 mice (d) than in C57 mice (c).
e and f Immunoflorescence of HUVECs with anti VE-cadherin antibody. Cell-cell adhesion was different in Slit2 stimulated HUVECs (f) compared with cells not stimulated with Slit2 (e).
g Slit2 increases the permeability of HUVECs in in vitro permeability assays. The Robo blocking antibody R5 could block this effect.
